Golyad (Russian: голя́дский язык) or East Galindian (Latvian: austrumgalindu valoda, Lithuanian: rytų galindų kalba) is a poorly attested extinct Baltic language of the Dnieper Balts living in the Protva basin in present-day Russia. The Golyad people are believed to have descended from the Moshchiny culture and is the only known ethnonym for the Dnieper-Oka language. Due to there being no known written documents of the Golyad language, the language is poorly known. The language went extinct in the 12th century due to Early Slavic migration and assimilation. It is believed the vernaculars of the Finno-Ugrians and Volga Finns adopted loanwords from East Galindian.
